A further object of the invention is to provide a device of thecharacter set forth which is extremely simple in construction andeconomical to manufacture. I

lVith th foregoing and other objects in view, the invention consists inthe novel features of construction and combination of parts which willbe more fully described. hereinafter and particularly pointed out in theclaims. V In the drawings accompanylng and forming part of thisspecification,

The same characters of reference designate the same parts in thedifferent figures ofthe drawing. V

Referring tothe drawing, E designates a tube such as is commonly used bychemists and others for the reception of creams, ointments, etc. Theimproved filling device con-- sists of a pair of channel members A andB, of semi-circular form in cross section. The member A is somewhatlonger than the tube with which it is intended to be used, and is ofsuch diameter that it fits snugly within said tube. This member A isentirely open at both ends thereof, and is provided at one I i end witha lug D extending at right angles therefrom at its periphery, forpermitting the withdrawal of the member A from the tube E after thelatter has been filled.

and is of a diameter sulficiently large to'perm1t it to snugly'fit theexterior of saidtube. This member 'B is provided at one end thereofWithan internal disk C which is adapted to form a piston within themember use in the manner hereinafter described.

The operation of the device is as follows: The substance to beintroduced into the tube E is first deposited in the member A, thismember is then inserted within the tube E as far as it will go. Themember B is then placed on the exterior of the tubeE in diametricallyopposite relation'to the member A. Thereupon the member B is slid alongthe tube E so that its disk piston C engages the material within themember A and forces 7 it up 1nto the tube E, the sliding movement of Bbeing continueduntil the disk Cis'in engagement withthe end of the tube,where'- upon theoperator'will hold it in this position while hewithdraws; the member A by taking hold of the tube.
